The gauging portion f243 `on the blade .18 is a greater distance from theouter face of plate 11? than is thegauging portion 22 ofl blade 17, and this greater distance, designated B, is slightly greater than the maximum permissible for satisfactory operation of a coupling. The gauging portions 22 and 23 row gauging edge as is shownin Figs. 2, 3 and 4.

Y Theblade 17 is provided withaitiextensiomv the outer edge 24 of which iswarranged parallel` to the axis of plate ll'and is spaced therefrom predetermined distance. l A gauge blade 25 ispositioned in the outer end plate 11.

A rbore is provided through theboss12, 'ygilatel 11- and memberv 13 4and contained in said bore isavv bushing `45. lA bolt 27 is rotatably .mounted in1 a,

'The member 32'r carried by the bolt 27v saidfarm being determined by dowell pins 35'.'A Se.- "cured in the end of arm`37 by meansvvof a. bolty 39 and positioned by dowel pins 38 `is .a gauge blade A40 having a concave gauging portion'.41,

The concave gauging portions 26 and41 of the" gauge blades 25 and 40 are preferably beveled'as shown in Figs. 2, 3 and 4v to, provide vanar'rowH gauging edge. The verticaldista'ncfe Clfromfthe outerfac'e of the gauge ring 11`to the gauging surface 26 ofthe blade 25 represents the mai'iimuml permissible distance fromthe 'coupling face 4 of the hos'e coupling to the rib 9 on the locking outer face of gauge ringV 11 to the gauging surv face 41 on blade v,40 is slightly less thany the min- -imumdistance required between the coupling f face 4, of the 'hose-'coupling andthe rib v9 tol en- 75( visure satisfactory functioning of thecoupling.I "f

is'lslotted, 'and mounted in the slot isv an arm v37 which is secured in place by a bolt 36, the positioning ofv flange' 8, while the Vertical distance'D 'from the To use the gauge, the arm 3"?A carried by the member 32 is turned away from the arm 19 a somewhat greater distance than shown in Fig. 1. The gauge is then applied to the hose coupling 1, the boss 12 entering the bore 3 and the circular plate 11 engaging the coupling face 4 of the coupling. The gauge is then turned on the coupling in a counter-clockwise direction, as viewed in Fig. 1. If` the groove 6 invguard arm 5 is not too close tothe face- 4 of the coupling; the-gauging `portion 22 of blade 17 freely enters said groove, while at 'substantially the same time, the gauging portion 260i blade 25 moves over the rib 9 on the lockving' flange 8`if said rib is not too 'far from the of blades 17 and 18 are lbeveled to obtain a nar-1r couplingA face 4.. 'The gauge is then turned furtherin the above mentioned direction and if the Agrooved-in guard-arm' is not too far away from the couplingiace 4 of the coupling the gauging portion 23 of the blade 18 engages the guard arm .5 andthereioi'e does not enter the groove 6. The movable arm 37 is now turned towards the lockof the VU-shaped'arm 19 by dowel pins 46 andis7 secured thereto bya bolt 47 land is provided'withy aconcave gauging portion 26 the contour" of which corresponds substantially to the contour' ofthe rib '9,oi the locking flange 8. The inner# vertical edge 420i the blade 25 is spaced a preH determined distance from the central axis of 'L iverticaldistance from the coupling face 4 to groove rintheguard armv andy this distance must be'within `the limits defined by the gauging portions of said blades to besatisfactory for use. Also, the gauging portions' 26 and 41 of the blades 25 and 40,.' respectively gauge the vertical the locking ange 8, and this distance must be within the limits defined by the gauging portions of said" bladesto be satisfactory for use.

I',Iheveiti'cal""edge 240i the blade 17 and the vertical edge 42 of blade 25 being both located a predetermined distance from the longitudinal axis of` the boltf27 provide :a means by which having a bore in which the portion'29r of the bolt" 27jis mounted is 'secured against the washer 31"v 1 by means of'a1nut33 screw-threaded to the outer ac liecker'mayv visually ldetermine whether the machined surface 7 on theguard arm and 10 on flarig'eid'canbe accurately and quickly determined within'predetermined limits, and also the "condition of 'the'i'nachined surface on the outer face of theguard arm and thaton the body iange "adjacent the j lockingflange can be determined.
